Abstract In WDM networks, the bandwidth request of a traffic stream can be much lower than the capacity of a wavelength. Traffic grooming can aggregate low-rate connections onto high-capacity lightpaths to make full use of the bandwidth. But most of the researches related to traffic grooming has focused on ring networks, and fewer concerns are about the dependable traffic grooming of low-rate connections in WDM mesh networks. In this paper, a Shared Protection Traffic Grooming algorithm is proposed based on wavelength Layered-Graph (SPTG-LG) considering both the survivability and traffic grooming in WDM mesh networks. Some simulations and analysis are also given out.
